Abstract

Meningkatnya usaha laundry di Kota Surabaya menyebabkan peningkatan limbah cair yang dihasilkan. Hampir semua limbah cair dari usaha laundry tersebut dibuang melalui selokan atau tangki septik tanpa proses pengolahan terlebih dahulu sehingga berpotensi menimbulkan pencemaran tanah dan badan air di sekitarnya. Limbah cair usaha laundry memiliki nilai TSS 560 mg/L dan surfaktan 186,4 mg/L yang melebihi baku mutu mengikuti Peraturan Gubernur Jawa Timur No. 72 Tahun 2013 yakni 100 mg/L untuk TSS dan 10 mg/L untuk surfaktan. Salah satu cara mereduksi kadar pencemar dalam limbah cair adalah dengan menggunakan filtrasi membran. Zeolit dan kitosan merupakan bahan yang sering digunakan sebagai bahan membran karena memiliki kemampuan yang baik dalam dalam membentuk film, pengolahan mudah dan ketersediaan yang melimpah. Penelitian ini bertujuan untuk menganalisis pengaruh penggunaan membran dari sintesis zeolit dan kitosan terhadap nilai fluks, rejeksi kadar TSS dan surfaktan pada limbah cair usaha laundry. Proses filtrasi menggunakan aliran cross-flow karena memerlukan biaya operasi yang lebih rendah. Variasi yang dilakukan dalam penelitian ini yaitu perbandingan komposisi massa zeolit dan kitosan 1:1; 2:1 dan 1:2 (Z1C1; Z2C1 dan Z1C2) dengan total massa yang digunakan yaitu 15 g, serta variasi tekanan 1,5 bar dan 2 bar. Sedangkan limbah yang ii digunakan yaitu limbah cair laundry dengan konsentrasi 100% tanpa penambahan air suling atau pengenceran. Dari penelitian diperoleh data perbandingan komposisi zeolit dan kitosan optimum, nilai fluks dan nilai rejeksi membran. Perbandingan komposisi membran yang terbaik yaitu perbandingan zeolit dan kitosan 2:1 (Z2C1). Nilai fluks tertinggi didapatkan dari membran Z1C1 tekanan 2 bar pada menit ke-10 yaitu 39,99 L/m2.jam. Sedangkan efisiensi removal TSS dan surfaktan tertinggi masing-masing pada membran Z2C1 tekanan 2 bar pada menit ke-20 dan membran Z1C2 tekanan 1,5 bar pada menit ke-60 yaitu 90,71% dan 97,67%. =========== The increasing number of laundry industries, has caused the increase of wastewater generation. Nearly all wastewater from the laundry busines is disposed of through a sewer or septic tank without any advance processing, so that potentially caused contamination of soil and water. Laundry wastewater has a concentration of TSS 560 mg/L and surfactant 186,4 mg/L where the levels exceed the quality standards in East Java Province of 100 mg/L for TSS and 10 mg/L for the surfactant. One method to reduced the pollutant in wastewater was using membrane filtration. Zeolite and chitosan were materials that have been often used as membrane material because it have a good ability in the film-forming, easily processing and availability of abundant. The aim of this research is to analyze the effect of using membranes synthesized from zeolite and chitosan for flux and removing pollutants mainly for the parameter of TSS and surfactant in laundry wastewater. The filtration process used cross-flow method because it required lower operating costs. Variations in this research were the mass composition ratio of zeolite and chitosan 1: 1; 2: 1 and 1: 2 (Z1C1; Z2C1 and Z1C2) with a total mass used of 15 g, and variations in pressure of 1,5 bar and 2 bar. Where as the concentration of wastewater used in the process was 100% without the addition of distilled water or dilution. iv The research data showed composition ratio of optimum zeolite and chitosan, the membrane flux and rejection or removal efficienciy. The optimum compotition ratio of zeolite and chitosan was 2:1 (membrane Z2C1). The highest flux in membrane filtration was membrane Z1C1 in pressure of 2 bar at 10th minute that was 39,99 L/m2.jam. Where as the highest TSS and surfactant removal efficiencies at Z2C1 membrane pressure of 2 bar at 20th minute and Z1C2 membrane pressure of 1,5 bar at 60th minute were 90,71% and 97,67% respectively.
